6.3.3 PD-HDWR and PD-HDWR-MBS Terminal Block Connections
Conduit entry holes are provided on the rear and side of the box. Input and output wiring should not
share the same conduit.
The standard PD-HDWR comes installed on the UPS. The PD-HDWR-MBS with manual bypass
switch is optionally available. Both have the same hardwire terminal connections.
For best performance, distribute all L-N loads evenly between L1 and L2.
6.3.4 PD-001 Power Distribution Box
An optional PD-001 is available to provide the conve-
nience of an L14-30P input plug and output receptacles.
To use this box, remove the original PD-HDWR hardwire
box and install the PD-001.
